Ziyatdinova, G.K. Chronoamperometric determination of synthetic phenolic antioxidants in Brij 35 micellar medium / G.K. Ziyatdinova, K.S. Os'kina, E.R. Ziganshina, H.C. Budnikov // J. Anal.Chem. – 2015. – V.70. – № 12. – P.1501-1506. |
| Аннотация |
tert-Butylhydroquinone (TBHQ) and tert-butylhydroxyanisole (BHA) are oxidized on a glassy carbon electrode modified with multiwalled carbon nanotubes in a 0.1 M LiClO4 supporting electrolyte in the medium of 1 mM Brij?35 at 0.27 and 0.47 V, respectively. A method for their chronoamperometric determination is developed. It is shown that a steady-state electrolysis is achieved within 100 s. The analytical range
is 2.50?1000 μM for TBHQ and 1.50?100 and 250?1000 μM for BHA with the detection limits (S/N = 3) 0.64 and 0.38 μM, respectively. The relative standard deviation in the determination of TBHQ and BHA in model solutions does not exceed 6%. The method was tested on micellar extracts of linseed oils. The accuracy measure is 100 ? 1%, which points to the absence of matrix effects in the determination of TBHQ and BHA. |
